Question

Life Science Help?!?!?! I will fan and medal!

Answer 1

Which is true of genes found on chromosomes?




They cause mutations when they make substitutions or deletions to RNA.



They are the site of protein manufacturing.



They cause mutations when they make substitutions or deletions to DNA.



They determine the inherited traits of an organism.

Answer 2

I can help

Answer 3

Okay

Answer 4

I would say the last one, if you look up the definition of the gene then part of the definition is the last option which makes it true

Answer 5

Okay, what about this one:

What is the relationship between a mutation and a gene?




A mutation changes the sequence of DNA bases of a gene.



A mutation creates new genes from the same DNA segment.



A gene causes a mutation when it manufactures the wrong protein.



A gene results in a mutation when it produces a change in the type of mRNA.

Answer 6

The first one

Answer 7

Medal if I helped :)

Answer 8

I have a few more. Can you help?

Answer 9

ok

Answer 10

This is the normal nucleotide sequence on a DNA strand:

A—C—T—G—G—A—T.

What is an insertion?




A—C—T—G—C—G—A—T




A—C—T—G—A—T



A—G—T—G—G—A—T



A—C—T—G—G—A—U

Answer 11

I would say the third one, but I'm not sure

Answer 12

Which of these is a case of selective breeding?




To increase the production of milk in a herd of milk cows, the highest producing cows were chosen as the mothers.



Over time, more milk cows at the diary farm began to produce larger amounts of milk.



A gene was identified that increased milk production. This gene was added to calves in the womb.



The genome of a group of cows was analyzed to identify the gene for milk production.

Answer 13

The first one

Answer 14

Which statement describes an example of gene therapy?




A virus is used to transfer human DNA into a bacterial cell.



A defective gene is replaced with a normal gene.



DNA banding patterns are used to identify an individual.



The genes for a certain desirable trait are identified.

Answer 15

You there?

Answer 16

second one

Answer 17

When you get back, please give me a medal I've answered at least 5 of your questions

Answer 18

I did medal you, and also, just a heads up so you can't get suspended, you are not allowed to ask for medals, the person has to do it themselves.
